WID-SEC-2026-1566 · first 18.05.2026 · updated 16.07.2026 · CVSS 7,3
What it is about
Open Source Argo CD ist ein deklaratives, GitOps-basiertes Continuous-Delivery-Tool für Kubernetes. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Argo CD ausnutzen, um Informationen offenzulegen oder Cross-Site-Scripting-Angriffe durchzuführen, wodurch potenziell Administratorrechte erlangt werden können.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- Informationen offenzulegen oder Cross-Site-Scripting-Angriffe durchzuführen
- wodurch potenziell Administratorrechte erlangt werden können
Am I affected?
Affected according to the BSI:
- Open Source Argo CD <3.2.12
- Open Source Argo CD <3.3.10
- Open Source Argo CD <3.4.2
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Argo CD 3.2.12
- Open Source Argo CD 3.3.10
- Open Source Argo CD 3.4.2
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
